What app can help me sell logo apparel online?

Update: Figured out that I think I was just using Printiful incorrectly, should be good to go now. 

Hello, apologies if this question has been asked, I didn't quite find the same question. I am trying to find an app to integrate with my store that will allow me to sell shirts and hats with my company logo on it. I do not want the customer to be the one to customize the item, just to select the items that I have already created. 

Are there apps that offer this feature?
